Changes in directory llvm/lib/Transforms/Hello:

Hello.cpp updated: 1.6 -> 1.7
---
Log message:

Make this example pass use some things from lib/Support (EscapeString,
SlowOperatingInfo, Statistics). Besides providing an example of how to
use these facilities, it also serves to debug problems with runtime linking
when dlopening a loadable module. These three support facilities exercise
different combinations of Text/Weak Weak/Text and Text/Text linking 
between the executable and the module.
